Definitions
- Lyme disease is the most common tick-borne infectious disease in humans. A significant part of the ticks, which serve as vectors for the transmission of Lyme disease, is infected with the causative agent of Lyme disease, the spirochete Borrelia burgdorferi. Depending on the geographical area, the degree of infection can be between 1 ° and b s to 100 ° s.
- infection with B. burgdorfe ⁇ run subclinical. However, it is often problematic to have late effects caused by unrecognized or untreated Borrelia infections. Especially because of the dangerous diseases that can occur in unrecognized or untreated infections, such as carditis, myositis, ulceris, panophthalimitis or neurological manifestations, it is important to prevent any infection with B. diagnose burgdorfer as safely and accurately as possible.
- the pathogen detection can be carried out from patient material, particularly in the early stages. However, it is disadvantageous that the cultivation of B. burgdorferi is relatively difficult and is therefore usually reserved for special laboratories.
